Young Thor: Look brother, mother has set cookies!
Friga: You shall not eat these sweets until you have finished your supper
Young Thor: ...
Young Thor: *brings Loki over his head*
Young Loki: Brother what are you doing!? Thor--!
Young Thor: HELP MY BROTHER IS DYING GET HELP *tosses Loki full speed*
Young Thor: *grabs cookie jar and runs to secret room that little Thor and little Loki probably had idk*
